/* ==========================================================================
   inphner: inphub's "Glass" design system, applied to a speedcubing timer.

   Floating, rounded, translucent panels over a slowly drifting colourful
   wallpaper. Everything is switched by attributes on <html>:
     data-theme      dark | light
     data-accent     blue | indigo | purple | pink | red | orange | green | teal | graphite
     data-wallpaper  aurora | sunset | ocean | forest | graphite | plain | custom
     data-glass      full | reduced
     data-logo       accent | wallpaper
   Token values are copied from inphub verbatim (inphner-prompt.md, Part B).

   Four rules that are easy to break (see CLAUDE.md):
   1. Only <html> paints the base colour. Never give body/.app/.main/.view a
      background: it would cover the z-index:-1 wallpaper.
   2. Animations on containers that hold glass use fill mode `backwards`, never
      `both`/`forwards`, and no transform/filter is left on a glass ancestor.
   3. Overlays put their tint + blur on ::before, never on the element that
      contains the glass box.
   4. --bg, --text-dim, --border, --accent, --good, --warn, --bad, --purple stay
      plain colours (never color-mix()): charts read them at draw time.
